BLAST-LOADING DEVICE.

Specification of Letters Patent.

Patented Aug. 1, 1905.

Application filed T-ily8,1904. Serial No. 215,714.

Ton/ll whom, it may concern:

Be it known that we,EGBERT CORNELIUS and BURTON G.Co1 n, citizens of the United States, residing at Orrville, in the county of Wayne and State of Ohio, have jointly invented certain new and useful Improvements in Blast Loading Devices; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being bad to the annexed drawings, and to the figures of reference marked thereon, in which Figure 1 is a sectional view of the funnel, showing the same properly attached to the top or upper end of the feed-tube, showing the valve properly located and mechanism for operating the valve. Fig. 2 is a detached view of the combined gage and wire-holder.

Fig. 3 is a view showing anumber of sections of the feed-tube and the different parts properly arranged With reference to each other. Fig. 4 is a detached view showing a portion of the slotted or open blasting-material-de- Fig. 5 is a detached View of the tamping-plug. Fig. 6 is a detached view of a portion of one section of a feed-tube. Fig. 7 is a detached view of one of the section-couplings. Fig. 8 is a view of the explosive holder.

The present invention has relation to blastloading devices especially designed to convey the blasting material to the place or point where it is to be exploded; and it consists in the novel arrangement hereinafter described, and particularly pointed out in the claims.

Similar numerals of reference indicate corresponding parts in all the figures of the drawlngs.

In the accompanyingdrawings, 1 represents the feed-tube, which is preferably formed in sections, and the sections connected together by means of the couplings 2, by which arrangement a feed-tube of any desired length or of various lengths may be produced, as it will be understood that the number of sections may be increased or decreased, owing to the difierent depths of the drill-holes.

For the purpose of providing a means for feeding blasting-powder into the feed-tube proper the funnel 3 is provided, which funnel is provided with the downward-extending flange 4, which flange embraces the top or upper end of the feed-tube 1, as illustrated in Figs. 1 and 3.

For the purpose of supporting the funnel the flange 4 is provided with the rib 5, located upon the inner periphery of the tube 4, and

is so arranged that said rib will rest upon the top end of the tube 1.

The funnel 3 is provided with the valve 6, which valve consists of a ball formed of a size to close the lower end of the funnel 3, and for the purpose of opening the funnel, so as to allow blasting material to enter the tube 1 and be conveyed through the tube, the valve 6 is provided with the arm 7, which arm is pivotally connected to the flange 8 or its equivalent, and for the purpose of holding the valve in an elevated position the spring-catch 9 is provided.

To the bottom or lower end of the feed-tube 1 is attached the delivery-section 10, which delivery-section is provided with the slot or opening 11.

The delivery-section 1.0 is formed of brass or like material or of such material that will not strike fire by coming in direct contact with the explosive material.

It will be understood that brass or like material will not cause an explosion of powder by coming in contact therewith, and hence the necessity of employing brass or like material for the explosive-delivery section.

To the bottom or lower end of the deliverysection 10 is attached the tamping-plug 12, which tainping-plug is preferably formed of wood or other fibrous material.

For the purpose of shunting the blasting material so that it will passthrough the opening 11 the top or upper end of the tamping-- plug 12 is tapered substantially as illustrated in the drawings.

In use the various sections of the feed-tube are connected together so as to produce a tube of the desired length, the lower section being provided with the tube 10 and the plug 12, the tube, together with these parts, being lowered into the drill-hole, by which arrangement the blasting material is conveyed through the tube without coming in contact with the surface of the drill-hole until it reaches the opening 11, which opening is located just above the point where the blasting material is to be deposited, thereby preventing any choking or clogging of the blasting material during the time it is conveyed to the bottom of the drill-hole.

It will be understood that during the time powder is conveyed to the bottom of the hole the feed-tube sections, together with the tamping-plug, may be given a reciprocating movement by hand or otherwise, thereby tamping the powder, it being understood that the powhe opening 11 as they come 2 upper tapered end of the ;tood that the sticks of dyexploded, owing to the fact e wood plug 12 and are suriss tube 10 at the time they ed to explode the powder :h has been placed in posiacribed, the feed-tube, tolerent parts, is withdrawn holder 13 is attached to the nd of the tamp'ing-plug 12 amite inserted in the lower the wires 14 being first atof dynamite in the ordiich wires extend upward is of the feed-tube, as illusnd the upper ends of said theholder 15, after which gather with the different reto, is again placed in the 4: are now detached at their e tube withdrawn, the wire ining in position and prople stick of dynamite. i of allowing the feed-tube ie diflercnt parts attached the holder 13, to be withis provided with the slot pen at its bottom or lower For the purpose of connecting the tampingplug 12 to thebottom or lower end of the delivery-tube 10 the pin 17 is provided; which pin is preferably formed of wood.

The delivery-tube 10 is shown provided with a single slot or opening.

It will be understood that the number of openings may be increased, if it is desired that is to say, that an opening may be formed in the tube opposite fnom that shown in the drawings. I

The gage and holder 15 consists of a springband provided with flanges 18, which springband is clamped upon the upper tube-section by means of the thumb screw 19' and the hooked flange 20.

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In a blast-loading device, the combination'of afeed-tube, a delivery-tube connected thereto, and a tamping-plug located directly below the deliverytube and an explosiveholder adapted to be attached to the tampingplug, substantially as and for the purpose specified.

2. In a blast-loading device, a tube and a funnel connected thereto, said funnel provided with a valve, explosive wires and a hook adapted to hold said explosivewires, said hook carried by the tube, a delivery-tube and a tamping-plug secured thereto, all arranged substantially as and for the purpose specified.

In testimony that we claim the above we have hereunto subscribed our names in the presence of two witnesses.
